juddering and shaking

[G@NDY]

Got a few problems with my whip (dont know what that phrase means really just thought i would use it)
Just did this for the first time yesterday. When reversing there is a juddering at the backend, think it could be wheel hop?? not sure. I do have an unfitted diff brace which im hoping cures it!! any ideas?

Also when driving slowly say at 30, the car is fine on throttle just cruising but when you take your foot off the accelerator the whole car shakes about, then its fine again if you select a lower gear or put your foot back on the gas. Now this has got me thinking, thought initially engine mounts, but the engine has been out more times than ... well alot. And no one said they needed replacing so hope they are okey, then thought it could be because of the state of tune of the car (the 1680cc secondary injectors) and maybe also the lightened flywheel:xconfused :rolleyes:
I thought that buying an engine torque brace might fix this???

Yeh, Sounds like a Mount or UJ joint some thing like that.

Are you sure every thing is tight if the engines been in and out alot?

No mate, as it wasnt me that did it. Anything in particular I should check?

[G@NDY]

Been thinking about this some more, and if something was loose or it was a mount wouldnt it do it at high speed aswell??, and possible have trouble getting it in gear? It almost feels like when your going 20mph in fifth in a normal car and its having trouble because of the low speed?:confused:

I\'ve been thinking about it too, Check your Front Diff mount, if that is worn or damaged it will allow the front of the diff to move out of line causing the prop to wobble. I\'m not 100% sure if it would do it all the time but i\'ve sen it happen on another make car.

Does it do it more with load on, crusing or over run?

[G@NDY]

Front diff mount right oh mate, will get that checked.

It doesnt do it on throttle or at cruise or on WOT, just does it when im in say 3rd doing 30mph and come off the throttle completely to slow down. it then judders and if throttle is re-applied it goes away:rolleyes:

Sounds like a faulty differential mount

[Grizzly]

Don\'t go giving it any bean until you get it checked, Fd\'s don\'t like bad Diff mounts they tend to brake the cases.

Would his clunking at low speeds be caused by maybe by the diff its self on its way out?

Mine has just started to make clonking noises last night when I do very low speed turns or reversing, I might get it stuck on a ramp to check the diff mounts or its a replacement diff time

tis prob your diff mounts matey, mine are on the way out and do the same as yours...... its like when you try to pull away from a junction in 2nd or 3rd.

tis prob your diff mounts matey

Right oh then, is this a big job??? would i get away with just fitting my diff brace ? or is it best to get em changed and how much is this going to cost the gandalf???:rolleyes:

Just a thought the diff can be dropped without touching the gearbox? is that right?. Should be a pretty straightforward job then!!!
Will the mount have obvious damage and how many are there?

[banned advertiser]

You can change with out touching the g/box and there are 2, I would doubt you will see it without taking out unless really bad, I would take both out and inspect.

[rmagictastic]

i have heard that dropping the diff is a right pain in the butt?

Nar the Diff Bolts are usaly Very tight but its not a Hard job.

The clunking you can hear may be the back lash in the Diff, It may need New bearings in but i\'d suspect once you change the Diff mounts the noise will go (may be becouse its not sat properly in the car)
